I have a 1911 .400 corbon barrel and recoil spring. the barrel is stainless steel and is unused, it comes with a recoil spring but you will need to put a link and pin on it. the blued barrel is sold. I also have a set of u.s.gi plastic 1911 grip panels In brown color.
$50.00 for the barrel and recoil spring plus shipping
$10.00 for the grips plus shipping
I will trade both for a threaded barrel for the 1911
